High School Mental Math Posters

A simple skills poster that aims to explain, in simple terms, what an Irrational Number is. One important distinction of irrational numbers, is that even if a number sometimes might go on to infinity, it doesn't mean that it is an irrational number. This poster aims to help students understand this.

What is a Surd? This is a surprisingly slippery topic. As a teacher or tutor, we might have an understanding of what one is, but there are a lot of loopholes, traps and exceptions. This poster helps! We have found in our research that explanations of Surds often omit certain pieces of important information in order to generate a simpler understanding, only for the student to be told that there are some exceptions to the rules. This poster therefore aims to set a firm grounding on which to build an understanding of surds without having to navigate through the maze of exceptions and loopholes.
